Been looking through the search trying to find the differences, some say they are the same some say the hx moves more air, Which is right? Also will either of these work good on the truck in my sig ( found a whc1 cheap)or do I need something that moves more air like a stage 4 kit? Or been looking at H1E to do a hybird with its compressor and my exhaust. I will be pulling my 8 1/2 x 22 enclosed race car trailer 100-300 miles a week, its not real heavy but man does it catch some wind and pull like a led balloon . Just trying to get the best bang on a buget, race car has a big appetite for extra $$$$ . Thanks gang, Terry.

 

The WH1C used on 94-95 trucks has the same 56mm compressor the HX35 uses. It also has the same turbine side; one of the only differences is that the compressor housing clamps to the CHRA on the WH1C, whereas on the HX35 a snap ring holds it in place.

 

Ya what he said. Thats exactly right.

 

My WH1C gave out on me, and I have an HX35 now. No differences at all in spoolup, or EGT's. I wouldnt hesitate to buy either one.
